SEFFNER, Florida -- Florida rescue workers have ended their efforts to recover the body of a man who disappeared into a sinkhole that swallowed his bedroom while he slept in a suburban Tampa home, and the house will be demolished, a public safety official said on Saturday.

Jeff Bush, 36, who is presumed dead, was asleep when the other five members of the household who were getting ready for bed on Thursday night heard a loud crash and Jeff screaming.

Authorities have not detected any signs of life after lowering listening devices and cameras into the hole.

"Our data has come back, and there is absolutely no way we can do any kind of recovery without endangering lives of workers," said Hillsborough County Fire Rescue spokeswoman Jessica Dam.

The sinkhole also has compromised the house next door, officials said Saturday.

Officials planned to let family members, accompanied by firefighters, into the threatened home for about 20 minutes to gather some belongings, Hillsborough County Fire Rescue spokesman Ronnie Rivera told reporters Saturday.

She said demolition of the home would begin early on Sunday.

Bush's body hadn’t been removed by Saturday afternoon and the ground near the home was still "very, very unsafe," Rivera said at a televised press conference Saturday.

"At this time we did some testing and we determined that the house right next to the house that’s actually damaged is also compromised by the sinkhole," Rivera said.

"I really don't think they are going to be able to find him," Jeremy said on Saturday. He "will be there forever."

A small memorial of balloons and flowers for his brother had formed near the house on Saturday morning.

"I thank the Lord for not taking my daughter and the rest of my family," he said.

Jeremy himself had to be rescued from the sinkhole by the first responder to the emergency call, Douglas Duvall of the Hillsborough County Sheriff's Office. When Duvall entered Jeff Bush's bedroom, all he saw was a widening chasm but no sign of Jeff.

"The hole took the entire bedroom," said Duvall. "You could see the bed frame, the dresser, everything was sinking," he said.

Norman Wicker, 48, the father of Jeremy's fiancee who also lived in the house, ran to get a flashlight and shovel.

"It sounded like a car ran into the back of the house," Wicker said.

"There is a very large, very fluid mass underneath this house rendering the entire house and the entire lot dangerous and unsafe," Bill Bracken, the head of an engineering company assisting fire and rescue officials, told the news conference late on Friday.

"We are still trying to determine the extent and nature of what's down there so we can best determine how to approach it and how to extricate," Bracken said.

After suspending the search overnight, it resumed at daylight on Saturday, with engineering consultants trying to determine the extent of the collapse so that a perimeter boundary can be established for setting up heavy equipment for future excavation.

Several nearby homes were evacuated in case the 30-foot wide sinkhole got larger but officials said Friday it only appeared to be getting deeper. Soil samples showed that the sinkhole has compromised the ground underneath a home next door, engineers said Saturday.

The residents of that house were allowed 20 minutes in their home on Saturday to gather belongings. Firefighters and residents formed an assembly line to move items out of the house into SUVs and trucks.

Rescue officials said that in addition to soil samples, they were focusing on engineering analysis, ground penetration radar and other techniques to determine the extent of the ongoing collapse. Listening devices were being used to detect any evidence of life although Bush was presumed dead.

The Bush brothers worked together as landscapers, according to Leland Wicker, 48, one of the other residents of the house.

The risk of sinkholes is common in Florida due to the state's porous geological bedrock, according to the Florida Department of Environmental Protection. As rainwater filters down into the ground, it dissolves the rock, causing erosion that can lead to underground caverns, which cause sinkholes when they collapse.
